Blind decoding-based method and device for transmitting and receiving downlink channel in wireless communication system

A terminal comprising:

• at least one transceiver;
• and
• at least one processor connected to the at least one transceiver,
• wherein the at least one processor is configured to:
• transmit, to a base station through the at least one transceiver, capability information for a number of blind detections related to counting physical downlink control channel (PDCCH) candidates;
• receive, from the base station through the at least one transceiver, first configuration information for a monitoring scheme, and second configuration information for a first search space (SS) set and a second SS set related to PDCCH repetition;
• and
• perform monitoring and decoding for the PDCCH candidates, based on the first configuration information, the second configuration information, and the capability information,
• wherein each PDCCH candidate in a first monitoring occasion of the first SS set is counted as one, and each PDCCH candidate in a second monitoring occasion of the second SS set is counted as two.

A method comprising:

• receiving, by a base station from a terminal, capability information for a number of blind detections related to counting physical downlink control channel (PDCCH) candidates;
• transmitting, by the base station to the terminal, first configuration information for a monitoring scheme, and second configuration information for a first search space (SS) set and a second SS set related to PDCCH repetition;
• and
• transmitting, by the base station, the PDCCH to the terminal, based on the first configuration information, the second configuration information, and the capability information,
• wherein each PDCCH candidate in a first monitoring occasion of the first SS set is counted as one, and each PDCCH candidate in a second monitoring occasion of the second SS set is counted as two.
